About

Welcome to Machete Trail Madness, home of the toughest Ultramarathons in the USA and why we allow the longest cut off times of any Ultras out there. Machete Madness is more than a race; it’s a movement which started in 2014. We create experiences that push limits, test endurance, and connect people through grit, heart, and community. From ultramarathons like Machete Trail Madness to the legendary Machete Muertos 200; one of the hardest 200-mile races in the world. Every event we build is designed to challenge the body, humble the mind, and awaken the spirit. But what makes us truly special is the people. Our volunteers are the heart of every mile, staying up through the night, cheering, guiding, and making sure every runner has a fighting chance to reach the finish. At Machete Madness, we celebrate perseverance, culture, and the spirit of never giving up! Because out here, you either find your strength, or you make it. Come challenge yourself, very technical terrain and soul crushing climbs, but the awesome views are worth the effort. MUST register by 03/24/2027 to ensure you receive medal/buckle and participant shirt, the race will likely sellout well before that. Please review all the information on this registration page, all the way down to the bottom of the page as it will answer all your questions and provide you with links to our location and racecourse maps, but if you still can't find what you are looking for then reach out to us at machete@machetemadness.com

The Machete Madness Experience

This is a unique experience as it is more of a mental challenge due to the course format as it is very easy to finish a loop and quit, but our motto is Never Give Up so we will do anything we can to support you so you can get it done. You get to interact more with other runners since you are doing laps and running with each other, definitely a more interactive experience as you get to encourage and push each other to the finish line, your family and friends also gets to see you more often and you can pack lighter as you will have the chance to reload your nutrition and hydration at each lap you complete since the racecourse loops around into the Campgroup every lap.

More bang for your bucks

The FREE camping is worth the registration fee and your family can join you, not just the participant, in addition we have free professional photos at no additional cost to you, free participant shirts of great quality, and no charge for your pacer to run with you; by far the more bang for your buck of any race out there, the Machete Madness Experience, not just a race. The vision we have for our events is for people to make this the full Machete Madness experience, not just a race to show up and leave in a rush. We live a life that's always on the go, take a moment to smell the Roses.

NO REFUNDS
